11.7.2 For acceleration/deceleration control
Seven bits, D2 to D8, are used to set a driving profile for acceleration/deceleration.
The pulse rate vs. time draws an S-shaped curve. The shape of this S-curve can be changed according to the
values set to D2 to D7.
The image of the operation during acceleration or deceleration is shown below.
94 pulses
Note
each are necessary for acceleration and deceleration.
Usually, therefore, set 188 pulses
Note
or more (acceleration pulses + deceleration pulses) to perform acceleration and
deceleration. If the set number of pulses is less than 94
Note
during acceleration or deceleration, refer to
11.7.10
Example of acceleration/deceleration operation

acceleration)
Pulse width at startup

Acceleration pulse number or deceleration pulse number: 94 pulses
Note
Note
The number of pulses when startup time setting is one time is shown. If the startup time setting is two times
and four times, the number of pulses is 188 pulses and 376 pulses. It is twice further the number of the pulses
in acceleration/deceleration operation, and it is 376 pulses and 752 pulses.
